Large Current Fluctuation of EVOH Extruder
Sorun Belirtisi
During EVOH extrusion, main motor current fluctuates ±15-20%, affecting extrusion stability and product quality
Neden Analizi
Feeding amount unstable; EVOH melt viscosity is temperature-sensitive, temperature fluctuations cause large viscosity changes; unsuitable screw structure causing uneven melting
Çözüm
1) Loss-in-weight feeder for stable feeding; 2) Precision temperature control ±1°C; 3) Select dedicated screw; 4) Increase screw mixing section to ensure uniform melting
Temel Çıkarım
Current fluctuation is caused by unstable feeding, poor temperature control and unsuitable screw; system optimization is key
